Sahl ibn Ziyad, from Ibn Mahbub, from Ibn Ri’ab, from Jamil ibn Salih, from Al-Fudayl ibn Yasar, said: I said to Abu Abdillah عليه السلام, peace be upon him: “I stand in prayer and I see in front of me, in the direction of the Qiblah, excrement.” Imam عليه السلام said: "Move away from it as much as you can, and do not pray on the roads."
